    Okay I feel kinda stupid but how do you convert mm to meters to the fourth power (unit = m^4)?

    Say you want to raise 22mm to the fourth power and have the answer come out in meters to the fourth. How do you do it?


    I know that mm=.001m, and that
    mm^2 -------->x10^-6 m^2

    thanks in advance

    Are you sure you want m^4 and not m * 10^4?

    no the unit i want is m^4, or meters to the fourth since I'm trying to take 22mm to the fourth power.

    (22)^4*(.001m)^4

    (.022m)^4 = 2.34256 * 10^-7 m^4

    thanks guys. I think the answer in the back is wrong then. My numerical answer was 1338.1 N m, but in the back they have it as 133.8 kN m, which i have no idea how they got.

    God damn mechanic textbooks always have errors in their god damn solutions page :mad:

    thanks again.
